Online casinos feature all the same games as land based casinos. In both land based and safe online gambling site casinos the most common games are the slot machines. There are several different variations of slots but the most popular will be the ones that offer a progressive pool. These progressive machines offer jackpots that reach in to the millions. What determines the jackpot is both the recognition of the machine as well as the size of the network which it is attached to.

Progressive slots have the highest jackpots of all slot machines. This really is because a small piece of each bet is placed into the jackpot pool. These machines might also be part of a network of slot machines that all contribute to the exact same progressive pot. These networks can even span more than one casino. The better machines that will be contributing, the faster the progressive pot grows. When the winning combination comes up at anyone of these progressive machines the player wins the full jackpot.
